Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a film unit with a lens constituted so that the malfunction of a photographing mechanism is eliminated by smoothing the rotation of a lock lever. SOLUTION: A C-shaped projected line 81 being the rotary shaft of the lock lever 59 is integrally formed at the rotation center of the lever 59. Then, one part of the outside circumference of a counter plate enters the part of the lever 59 where the line 81 is not formed. A notched part 82 notched by eliminating one part is formed at the line 81. The upper end surface 81a of the line 81 other than the notched part 82 abuts on the lower surface of a top board 63. Thus, the lever 59 is prevented from floating up and shake is prevented from occurring at a rotating time.
